During the hot summer months, the compost heap can quickly dry out. You can recognize this, among other things, by a cracked, crumbly surface - and by the fact that ants are suddenly cavorting on it. However, compost that is too dry is not an ideal environment for the compost and earthworms, which are so important for decomposition, which will therefore withdraw. The result is that the rotting process stops. You can prevent this by regularly reaching for the watering can.

If the compost is very dry, a little water is good for it

Why you should water compost

A compost pile needs sufficient moisture to keep the rotting process going on inside it. The earthworms and compostworms responsible for this only feel comfortable in a warm and humid environment, which is why they retreat when it is dry. But not only the disturbed rotting is an important reason for watering the compost: The heaps are often a source of fire because they can quickly ignite themselves, especially in sunny and hot locations. With a strong pouring from the watering can you counteract this danger effectively.

How to keep the compost pile moist

There are many reasons that cause a compost pile to dry out. The most important thing is the location: If the compost is in a sunny and warm place, it will dry out faster due to the location. Nevertheless, you should not move it if possible, since the compost worms, which are so important for the rotting process, also appreciate such a location. Instead, water more frequently so the material stays sufficiently moist. Another common reason, however, is the incorrect composition of the heap: If many dry, perhaps even woody parts of the plant are used for composting, it will dry out more quickly. It is better to layer the compost properly:

  • only ever layer thin layers of different materials on top of each other
  • Dry materials are always followed by wet ones, such as lawn clippings or leftover fruit and vegetables
  • If possible, chop up lignified plant parts and moisten thoroughly before filling
  • Always fill in a layer of mature compost soil in between
  • this inoculates the material with the microorganisms that are important for rotting

Water the compost properly - Here's how

In order to water the compost heap effectively and deeply - after all, the valuable moisture should also penetrate into the deeper layers - it is best to use a garden tool with a long handle, such as a hoe. Poke deep holes in the pile at regular intervals, stick first. Now pour the compost using a watering can with a fine attachment - this distributes the water better and more evenly and also reduces the water pressure.

tips

Although compost heaps should ideally be in sunny and warm locations, they benefit from shade providers such as shrubs or sunflowers planted around them.
